BURNER FOR LIQUID FUEL.

Specification of Letters Iatent.

Patented Oct. 3, 1916.

Application filed November 1, 1913. Serial No. 798,729.

To all whom it may concern 7 Be it known that I, JOHN JONATHAN KER- MODE, a subject of the King of Great Brit;- ain, and residing in Liverpool, England, at present temporarily residing in Petrograd, Russia, have invented certain new and useful Improvements in Burners for Liquid Fuel, of which the following is a specification. 3

This invention relates toburners for liquid fuel, and is an improvement on the in ventions described in the specifications of my prior applications for Letters Patents of the United States of America Serial Num bers 433555 filed May 1 81908 (which has matured into Patent No. 1,097,235, May119, 1914) and 748,649 filed February 15th 1913, and in describing my present invention reference will be made to the drawings of the said specifications. ments described in the said specifications relate to the detachable and renewable plate or plug 33 in which the nozzle is formed, to the spindle 3 and to the inner barrel 2. I find that a burner fitted with a detachable plug 33 constructed as described in the said specifications has considerable advantages, especially when it is desired to change the average rate of combustion, as for example from that necessary for full power to that necessary for cruising speeds only; in this case the plug suitable for full power can be replaced by one in which the nozzle is suitable for a rate of combustion corresponding with cruising speeds, thus insuring the highest efficiency obtainable under the respective conditions. In order, however, to obtain full advantage of this change, it is desirable that the size of the oil-ways 15 in the end of the barrel 2 should be modified to suit the size of nozzle in the particular plate or plug 33 employed, and the object of my present invention is to enable this to be done without taking the burner to pieces in order to remove the whole of the barrel 2. It is further desirable to so modify the construction of the nozzle plates that when made in an interchangeable series and used in conjunction with the spools, they are adapted not only to give various rates of feed of oil, but also to give different shapes of sprays suitable in respect to the degree of dispersion, and character of the spray for different requirements.

Certain of the improve- The invention is illustrated in the accompanyrng drawlngs in which a b Figure l s a longitudinal medial section of the complete burner; Fig, 2 is a similar 7 section, but toa larger scale, of the endv of the burner; and Fig. 3 a perspective view of the detachable end of the inner barrel. Fig. 4 is an end'view showing an adjustable indicating device on the hand wheel.

In the main the construction of the burner is similar to that described in thespecification to Letters Patent Number 1,097,235, and

the several parts herein are indicated by reference numerals corresponding with those whlch designate the corresponding parts in the drawings to the said specification.

The burner comprises a main body 1provided with an attachment flange 4; an inner barrel 2; a central spindle 3, having a hand wheel 20 graduated so asto givereadings relatively to the fixed pointer 21.

The oil enters at the oil inlet 6 and passes to the nozzle opening 9 by the annular pas- Y formed in the cap-nut.

According to the present invention the end 2 of the inner barrel 2 neXt to the plate 33 is made separate from the main part of the barrel, the transverse joint surfaces at a, between the two parts, being so shaped and prepared as to insure a proper fit between them these end pieces 2 are termed spools, and each barrel is provided with a number of such spools which are marked to correspond with the several nozzle plates or plugs 33 corresponding with various rates of com bustion; when therefore a nozzle plate 33 is inserted to correspond with the rate of combustion required, advantage istaken at the same time to fit the proper spool 2 to correspond with this, said spool being inserted fromthe front end of the burner when'the plate 33 is being changed. The abutting jointing surfaces between the main part of the barrel 2 and the spool 2 are preferably with the peripheral oil grooves 14, and the end grooves 15 formed in the enlarged portion 12, these grooves being arranged to suit the various rates of combustion for which the respective spools and corresponding plugs are designed.

A further improvement in the burner according to the present invention consists in modifying the shape of the nozzle plate, so a that in addition to bearing the rate at which the oil is supplied, the angle of dispersion of the jet and the character of, the spray maybe varied by changing the nozzle plate.

lVhen the nozzle plates 33 are interchanged it sometimes happens that the positions of the wheel 20 corresponding with the closed positions of the spindle for different plates do not quite correspond; it is therefore desirable to fit an adjustable zero pointer 20 adjustably fixed to the wheel by the spindle nut, as shown in Fig. 4, which pointer can be set to indicate the zero for the nozzle plate in use.

Having now fully described my invention, I declare that what I claim and desire to secure by Letters Patent is In a burner for liquid fuel comprising in combination a main body having an oil inlet,

an inner barrel and a central adjustable spindle, a spool fitting within the main body and against the end of the inner barrel, said spool having an enlarged end fitting the bore of the main body formed with peripheral and end oil grooves, a plate fixed to the end of the main body with the abutting surface of cylindrical and conical configuration and secured by a nut screwing on the main body, a nozzle-opening through said plate and a 'flat recess in said plate on its side remote from the main body determining the length of the nozzle-opening, said nozzle-opening communicating with the end oil grooves of said spool, a conical tip formed on the end of said adjustable spindle adapted to engage Gopies ofthis patent may be obtained for five cents each, by addressing the Commissioner of Patents,
